Specification of Letters Patent.

Patentedv Aug. 28, .1917.

To all whom t may concern:

Be it known that I, ALFRED L. PARMELEE, a citizen of the United Statesof America, residing at Lambertville, Monroe county, Michigan haveinvented new and useful Printing-Fresses, of which the following is aspecification.

This invention relates to presses for the multiplication of impressionsor copy.

This invention has utility when incorporated in a roll printing press.

Referring to the drawings:

Figure l is a perspective view of an embodiment of the invention in arotary printing press;

Fig. 2 is a showing of the inking and impression trains in operativeposition;

Fig. 3 is also a view of the inking and impression trains but with theinking and impression rolls thrown oif, the throw-off mechanism beingshown' Fig. 4 is an end elevation of the roll actuating train; -v

Fig. 5 is a fragmentary view of the inking train features;

Fig. 6 is a fragmentary perspective view of the cutting mechanism; and

Fig. 7 is a fragmentary detail view on an enlarged scale of the feeddriving connections.

The printing press embodies the cylindrical rotary ink fountain 1loosely mounted in the forks 2 by the shaft 3, said roller 1 restingupon the distributing roller 4 coacting with the supplemental inkdistributing rolls 5. The rolls 5 have their shafts 6 in the inclinedways 7 allowing these rolls to fall against the side of the roller 4which has its shaft 8 mounted in the lower part of the forks 2.

Disposed below the roll 4 is the live roll 9 of the inking train mountedon the shaft 10. This roll 9 coacts with the roll 4 and may coact withthe rolls 11 on the shafts 12 in conducting the distributed ink from theinking train to the copy 13 on the copy carrying roll 14 mounted on theshaft 15 having eccentric bearings. This copy carrying roll may transferits copy to the soft blanket or offset 16 on the first offset roll 17mounted on the shaft 18 which may in turn transfer from its blanket animpression to the blanket 19 on the se'cond roll 2O mounted on the shaft21 from which continuous copy impressions may be transferred to materialThis shaft 18 at its opposite end has theV herring-bone gear 32 in meshwith the herring-bone gear 33 on the shaft 15 which, through theherring-bone pinion 34 on the stub shaft 35 drives the herring-bone gear36 on the shaft 10. This gear 36 has the wrist pin 37 with 'universaljoint 38 connected to link 39 having universal joint 40 connected to thebell crank lever arm 41,l

mounted on the fulcrum 42, and its upper arm 43 connected by theuniversal joint 44 to reciprocate the shaft 3.

Accordingly the operation of the motor 26 rotates the shaft 29 and firstoffset roll 17. Copy roll 14 is a live or positively driven roll as isalso the inking train roll 9. The ink fountain roll 1 is reciprocatedacross the ALFRED L. PAEMELEE, OF LAMBERTVILLE, MICHIGAN, ASSIGNOR 0FONE-HALF TO distributing roll 4 and the rotation of the f' roll 9 istransmitted to these follower rolls 5, 4 and 1, as also to the followerrolls 11 for effective distribution of the impression substance to thecopy 13 on the copy roll 14. The herring-bone gearing precludes any lostmotion in the mechanism notwithstanding the throwing of the parts intothrow-off position, and this is also true of the spiral gear drive. Thesame diameter for copy 13 and roll 9 simplifies the throw adjustment.

ln mesh with 'the herring-bone gear 32 is the herring-bone gear 45 onthe shaft 21 of the second odset roll which is in mesh with theherring-bone gear 46 on the shaft 23 of the impression roll, ytherebymaking a positively driven impression or copy transfer train. Thetreadle 47 mounted on the fulcrum shaft 48 in the frame 25 is normallyheld upward by the spring 49 from the frame cross bar 50. When thistreadle 47 is .actuated against the resistance of the spring 49 andthrown into the latch 51, this tread lever acts, through'the link 52 andarm 53 to rock the shaft 54 in the frame 25. Connected to this rockshaft 54 is the pair of arms 55 from which extend upward the links 56connected by arms 57 to the eccentric bearings 2i of the impression rollFurther extension links 5S are connected by the arms to the eccentricbearings 6l for the shaft l5 of the copy carrying roll f4. These links5S have link extensions 62 connected to the angle lever (53 fiXedlyfulcrumed intermediate the rolls 1l and connected thereto by the arms(il. The arms of lever 63 have adjustable connections to vary the throw.Thismovement upward of the treadle -l7 rocks this angle lever G3 tothrow its central portion out of vertical position and accordingly throwthe rollers 1l outwardly in the guides (i5 medially between the shaftsl0, 15. This throws this lower pair of rollers of the inking train freeof the copy 13, while the upward travel of the links 5G, 58 actingthrough the arms 57, 60, has so thrown the eccentric bearings 24, Gl,that. the copy 13 is spaced to clear the first offset roll 17 while theimpression roll 22 is thrown away from the second offset roll 20.

The herring-bone gearingmaintains the operating registry between thetrain rollers notwithstanding the throw off' and the movement of theinking rollers of the impression train out of contacting relation.Accordingly, when the treadle is released, the former registry is had atonce.

The material to be supplied, as sheets of paper for copy, may be passedfrom the table 65 and the feeding occur automatically by the drivingmechanism from the shaft 2l of the second offset roll which has thereonthe mutilated gear G6 to drive the loose pinion 67 on the shaft 68. Thispinion (57 has the guide or holding recess (39 fo rest again-st theplate 70 adjacent the mutilated gear 66 in the range of the toothlessportion of said gear 66, thereby holding the pinion G7 from rotationexcept at the toot-hed portion of the gear 6G. This pinion (37 is inmesh with the pinion 7l fast on the shaft 72 carrying the stock feedingcams 73 and the additional cam 74, the latter acting to lift the bar 75against the resistance of spring 76 and thereby, through the rockshaft77 hold the fingers 78 in up position to interfere with the feed ofpaper stock. In the rotation of this shaft 72 when the cams 73 are instock feeding position the cam 7-l is in position to allow the fingers78 to be dropped by the spring 7G. The feeding of the paper is normallyguided by the guide fingers 7 9.

The travel of the stock from the table (33 as to the cam 73 isfacilitated by the pinion 7 driving the shaft 80 acting as a live roll.This shaft 8O is mounted in an oval bearing l and may have its clearancerelation as to the cam 73 adjusted by the thumb screw 82, forcing thepinion 79, 7l, into more or less depth of root register.

As the stock passes between the second offset roll 2O and the impressionroll 22, it. may be severed into the desired length sheets by thecutting edge or knife 83 anchored by screws Set into the slot in theimpression roll 22, scat 85 in theI second offset roll 2.0.

This printing press is of simple compact construction for a wide rangool' use in turning out superior work even on rough or low grade stock.The offset feature permits the i delicacy of reproduction from copyrequiring accuracy and minute showings even on the rougher stocks. tionmay occur with the usual copy which at the first impression gives theright or printing impression. This first impression is reversed b v thesecond ofl'set to give the final printing impression. Regular copy, sayvset up type, as well as cuts may be used as a projecting form copy onthis apparatus and s with superior results and a high degree ofsimplicity for job work.

Vl/hat is claimed and it is desired to secure by Letters Patent is:

A printing press embodying a frame pro- 9 viding a pair of opposingmembers, a bank of rolls mounted in said members including a firstoffset roll, driving means for said* offset roll, a copy roll on oneside of said offset roll, a second offset roll on the oppo;A S

site side of the first offset roll from the copy roll, an impressionroll beyond the second offset roll, gears on said rolls for transmi/ting driving action from the first offset rgll,` an idler gear by thecopy roll gear, an inking roll provided with a gear in mesh with saididler gear, an ink distributing roll provided with longitudinalactuating connection with said idler driven gear whereby said inkdistributing roll is reciprocated as to the inking roll, said bank ofrolls having their axes lying approximately in a common plane7 saidinking roll and copy roll being of similar diameter, and an ink applyingfollower roll actuated by the inking roll and coacting with the copyroll.

In witness whereof I affix my signature.
